The original problem was postconf failing to open main.cf and /etc/resolvconf/update-libc.d/postfix trying to copy /etc/resolv.conf onto itself at the line
because "postconf -h queue_directory" returns a null string. The bug is still present in postfix 2.9.1-2 and has nothing to do with "resolvconf: Error: /etc/resolv.conf must be a symlink" which all the duplicates, except #511314, *do* involve.
Somehow or other this report, #437783, or a clone of it, should be detached from all the duplicates and assigned to postfix.
